Hi all,
I have got engineering done for a slab for a house extension. There is an existing slab in place where the extension is going, but it is not up to spec for the engineers to be happy.
They completed soil tests and classed my site as H2. They propose the following (below diagram) for a 8.8m long and approx 6m wide slab. The slab will have a single story wooden frame and truss roof over it, it will become a master suite and part of the lounge room. Is this pure overkill for the area and should I go back and try and get this looked at?
I have received quotes for this slab for between 14-16k, does this seem right?
